How many frameworks are there in Qt?

I had read the Qt docs many times and sometimes I see some information about some frameworks in Qt like: Qt Quick Framework, Qt Model-View(-Delegate) Framework, Qt Graphics View Framework, Qt Concurrent Framework, Qt State Machine Framework, Qt Animation Framework, Qt Undo Framework. But I never see any docs that list all available frameworks on Qt (somethings like this docs for modules in Qt: http://doc.qt.io/qt-5/qtmodules.html ). I just want to know how many frameworks are there in Qt. Do you know?

i believe there is no official definition of such frameworks as you would like to see.
I understand Qt frameworks as a bundle of classes for a specific purpose. These frameworks are contained in different modules.
